It is also an example of Moderne architecture used for federal buildings in Texas. Its six Julius Woeltz murals, painted in 1940 under a New Deal arts program, are an integral part of its artistic significance.","narrative":"Completed in 1938 and dedicated in 1939, this limestone-clad federal building at 205 East Fifth Street in Amarillo combined a post office with a courthouse and federal offices. Texas architect Wyatt C. Hedrick designed it under the Treasury Department's Supervising Architect, using a restrained Moderne style on a pink granite base. Inside, the western end of the former postal lobby keeps its terrazzo floor, Montana travertine wainscot and six murals painted in 1940 by Julius Woeltz, depicting Panhandle settlement, cattle, oil and farming. The second-floor ceremonial courtroom retains its walnut wainscot and original bench, witness stand and clerk's desk. The building was listed for its link to Depression-era federal construction and arts programs, which provided jobs and public art, and for its architecture and murals. The post office moved out in 1977, and the building was renamed for Congressman J. Marvin Jones in 1980. It continues to serve as a federal courthouse and office building.","period_of_significance":"1938-1950","architect_builder":"Wyatt C. Hedrick, Architect; Louis A.
